[PATCH v5 0/2] Fix Omen 16-wf1xxx thermal profile and add EC readback

[Krishna Chomal]

This series fixes incorrect thermal profile parameters sent for HP Omen
16-wf1xxx and implements hardware readback support for Victus S thermal
profiles.

The first patch refactors the DMI handling for Victus S boards. By
moving from simple string list to DMI system id table with driver_data,
we can now map each board to its correct thermal parameters.

The second patch implements "get" callback for the platform profile API.
It reads the hardware state from EC register 0x59. This ensures that the
driver stays in sync with the hardware during driver init and power
source change events.

Changes in v5:
- Improved platform_profile_victus_s_get_ec() to support multiple EC
  layouts by iteratively probing offsets.
Changes in v4:
- Fixed driver load failure caused in v3
- Handle err after calling victus_s_gpu_thermal_profile_get()
- Fixed wrong function call victus_s_powersource_event()
Changes in v3:
- Moved DMI lookup to hp_wmi_init()
- Marked DMI table as __initconst
- Renamed `eco` to `low_power`
- Added second patch to implement "get" support for Victus S devices
Changes in v2:
- Refactored victus_s_thermal_profile_boards to use DMI table
- Implemented driver_data to handle thermal profile parameters
- Moved enum definitions earlier in the file for thermal profile
  parameters
Changes in v1:
  Initial fix for Omen 16-wf1xxx thermal profile values

[PATCH v5 1/2] platform/x86: hp-wmi: fix platform profile values for Omen 16-wf1xxx

[Krishna Chomal]

HP Omen 16-wf1xxx (board ID 8C78) currently sends the incorrect
Victus-specific thermal profile values via WMI, leading to a logical
inconsistency when switching between platform profiles.

The driver currently uses Victus S values:
0x00 => Balanced / Low-Power
0x01 => Performance

However, Omen Gaming Hub logs / EC register inspection on Windows shows
that this board is intended to use:
0x30 => Balanced / Low-Power
0x31 => Performance

This patch corrects the thermal profile command values to match the
values observed from Omen Gaming Hub logs. The performance benchmarks
and peak power draw (from both CPU and GPU) show no observable change
with this correction (suggesting that the firmware is currently tolerant
of the incorrect values). However sending the correct values prevents
potential regressions after future firmware updates.

Refactor victus_s_thermal_profile_boards from a list of strings to a
dmi_system_id table and move the lookup to module init. The new struct
thermal_profile_params is used to store board-specific WMI parameters,
allowing the driver to cache these values in a static pointer. This
avoids repeated DMI string comparisons and allows marking of DMI table as
__initconst.

Testing on HP Omen 16-wf1xxx (board 8C78) confirmed WMI codes 0x30/0x31
are now sent, resolving the logical inconsistency and ensuring the value
visible in EC registers match the Windows state for this profile.

Changes in v3:
- Fixed minor formatting issues.
- Renamed struct field `eco` to `low_power` for consistency.
- Marked the DMI table as __initconst.
- Moved DMI lookup to hp_wmi_init() and save the active thermal profile
  params.
- Added a static boolean flag to optimize is_victus_s_thermal_profile().
Changes in v2:
- Refactored `victus_s_thermal_profile_boards` to use `struct dmi_system_id`
- Implemented `driver_data` to handle thermal profile parameters,
  replacing the conditional checks in `platform_profile_victus_s_set_ec`
- Moved enum definitions for thermal profile values earlier in the file
  to support the new `struct thermal_profile_params`.

[PATCH v5 2/2] platform/x86: hp-wmi: Add EC offsets to read Victus S thermal profile

[Krishna Chomal]

The current implementation for Victus S thermal profiles only supports
setting the profile. The driver was missing the logic to read the
hardware state, meaning it would default to "Balanced" on driver load,
overriding the currently active profile. Furthermore, the driver could
not detect if the firmware reset the profile on a power source change.

Add platform_profile_victus_s_get_ec() to read the current thermal
profile state directly from EC offset 0x59. Since both Balanced and
Low-Power profiles share the same thermal profile value, differentiate
them by querying the GPU CTGP and PPAB states via existing functions.
Additionally, update the power source event notifier to use the actual
hardware state when re-trigger CPU power limits actualization.

Testing on HP Omen 16-wf1xxx (board ID 8C78) confirmed that the thermal
profile is now persistent across driver loads and power source change
events.

Changes in v5:
- Improved platform_profile_victus_s_get_ec() to support multiple EC
  layouts by iteratively probing offsets.
Changes in v4:
- Fixed platform_profile_victus_s_get_ec() to use both
  victus_s_thermal_params and omen_v1_thermal_params instead of
  active_thermal_params to fix regression caused in v3.
- Handle err after calling victus_s_gpu_thermal_profile_get().
- Fixed a wrong function call in victus_s_powersource_event().
Changes in v3:
- New patch in this series

I'm not so sure about this. Reading EC offsets and hoping we find the 
correct one doesn't sound the best idea. I'd prefer we store the 
information like we already do for thermal profiles. Unless there's some 
other way to detect which layout it is?

FYI, I took the first patch of this series again into the review-ilpo-next 
branch as it seems uncontested and fixes a problem in the existing code.

I explored the Omen Gaming Hub (OGH) behavior on Windows to see if a WMI
query exists for readback. OGH appears to default to "Balanced" on first
run and tracks state via a profile.json file on the disk. Deleting this
file causes the app to lose the current state, suggesting that there is no
official WMI readback query. By implementing EC reads, the driver can
actually remain more consistent with the real hardware state than the
offcial software.

I agree that iterative EC reads are not ideal. However, since these two
offsets (0x95 and 0x59) cover all (or almost all) known Victus/Omen layouts,
the risk of "hoping" is low.

Storing them at compile time in the victus_s array as a part of
.driver_data is indeed the best thing. But since we do not know what EC
layout is followed by the existing boards in the array, we can take a
hybrid approach here:
1. I (and subsequent additions) will store their EC offset in the
    .driver_data field struct.
2. For already existing boards we will perform this iterative probe once
    during init, and store it somewhere common.
3. Then platform_profile_victus_s_get_ec() can simply use this "definite"
    offset to perform the EC read.

I guess we'll have to settle to that but it likely means we'll never be 
able to source those offsets because things appear "working" and therefore 
cannot get rid of the extra code necessary for the EC offset iteration.

Another alternative would be to add pr_warn() if we don't have the EC 
offset yet for a board and not read anything (and hope somebody who has 
one of those boards will come to us with the information or patch).

Hi Ilpo,

That is a very fair point, if the driver just works, we would never get
the actual offsets. I have adopted a stricter version for v6:
1. I removed the iterative probing entirely.
2. Added a pr_warn() in setup_active_thermal_profile_params() for
    unknown boards.
3. Known boards (like 8C78) now have their offsets hardcoded in the DMI
    table.

This ensures that thermal profile readback is only enabled when we have
definite hardware data. I will send v6, based on the for-next branch,
shortly after thorough testing.

Thanks for the guidance!

[PATCH v6] platform/x86: hp-wmi: Add EC offsets to read Victus S thermal profile

[Krishna Chomal]

The current implementation for Victus S thermal profiles only supports
setting the profile. The driver was missing the logic to read the
hardware state, meaning it would default to "Balanced" on driver load,
overriding the currently active profile. Furthermore, the driver could
not detect if the firmware reset the profile on a power source change.

Statically store the known EC offsets for reading thermal profile in the
new .ec_tp_offset field of struct thermal_profile_params. Implement
platform_profile_victus_s_get_ec() to use this offset to read the real
hardware state. Additionally, update the power source event notifier to
use the actual hardware state when re-triggering CPU power limits
actualization.

Testing on HP Omen 16-wf1xxx (board ID 8C78) confirmed that the thermal
profile is now persistent across driver loads and power source change
events.

NOTE: Patch 1/2 of the v5 series (platform/x86: hp-wmi: fix platform
profile values for Omen 16-wf1xxx) is already accepted into
pdx86/for-next. This v6 contains only the remaining logic for EC
readback and is based on the for-next branch.

Changes in v6:
- Update struct thermal_profile_params to include .ec_tp_offset field.
- Use this field for reading from the embedded-controller.
- Add a pr_warn for "unknown ec layout" boards once during init.
Changes in v5:
- Improved platform_profile_victus_s_get_ec() to support multiple EC
  layouts by iteratively probing offsets.
Changes in v4:
- Fixed platform_profile_victus_s_get_ec() to use both
  victus_s_thermal_params and omen_v1_thermal_params instead of
  active_thermal_params to fix regression caused in v3.
- Handle err after calling victus_s_gpu_thermal_profile_get().
- Fixed a wrong function call in victus_s_powersource_event().
Changes in v3:
- New patch in this series.

Thank you for your contribution, it has been applied to my local
review-ilpo-next branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-next branch only once I've pushed my
local branch there, which might take a while.

The list of commits applied:
[1/1] platform/x86: hp-wmi: Add EC offsets to read Victus S thermal profile
